Application filed December 20, 1916. Serial No. 138,026.

To all whom it may concern:

Be it lmown tl it I, llaNs Pnirnnsnir, a citizen of the United .a'tates, residing at \Varrenton, in the county of Fairfax and State of Virginia, have invented new and useful Improvements in lVork-Holders, of which the following is a specification.

My present invention pertains to leather working, and more particularly to work supports of the expansible-holder type; and it consist-s i the peculiar and advantageous device, hereinafter described and claimed, designed more particularly for holding shoes of various sizes during the performance of work thereon, and the same in such manner that the hands of the operator are left entirely free and there is no liability of the work slipping or becoming marred, and yet when the work is completed the same may be expeditiously and easily released from the holder.

In the accompanying drawings which are hereby made a part hereof:

Figure 1 is a view, partly in elevation and partly in section, showing my novel device complete, as it appears when holding a small shoe.

Fig. 2 is a detailed section, taken in the plane indicated by the line 22 of Fig. 1, looking in the direction of the arrows and showing the leather facing on the body member of the holder.

Fig. 3 is a detail elevation showing the ar rangement of the holder when a comparatively large shoe is being held.

Similar numerals and letters of reference designate corresponding parts in all of the views of the drawings.

I illustrate in the drawings a floor F, a work-bench or other support B, and a shoe S, the latter being illustrated in dotted lines to make clear the mode of using my novel device.

Among other elements my novel work holder comprises a stand 1, having a base flange 2, fixed by screws 3 to the bench B. The stand 1 is provided with a bore 1 to receive the stem 5 of the body member 6 of the device, the said body member 6 being preferably, though not necessarily, removably arranged in and on the stand 1, for a purpose hereinafter described.

The said body member 6 of the holder is provided with a transverse opening 7, a removable filling-piece 8, of leather or other suitable material, and a facing 10, of leather or other suitable material, designed to be opposed to the sole of a shoe, Figs. 1 and 3, with a view to preventing blackening or other marring of the'sole. 'lhe filling-piece S is provided with end flanges 9, and the connection of the facing 10 is effected by screws 11. Y

Slidably arranged in the opening 7 of the body member 6 is a clamping member 12 which is preferably of the configuration illustrated, and is provided with a work-engaging portion 13 and a hook 1 1. Said hook 14: is for the engagement of a connection 15 that is interposed between the member 12 and a pedal lever T, pivoted on the floor F.

lnterposed between the clamping member at 18 and a connection 17 on the stand 1 a retractile spring 16 which is expanded when the member12 is operated through the medium of the treadle T and connection 1.5, and is adapted when the treadle T is relieved of pressure to contract and pull the member 12 into open position so as to permit of ready removal of the shoe.

In the practical operation of my novel device, the filling-piece 8 is employed when a shoe of small size is employed, and the shoe is interposed in the position illustrated between the portion 13 of member 12 and the facing of the body member 6. Pressure is thereupon applied to the treadle T with the result that the shoe is clamped and held between the members 12 and 6, and this so long as pressure on the treadle or pedal lever T is continued. lVhen, however, pres sure is removed from the pedal lever T, the spring 16 operates to pull the upper portion of the member 12 away from the facing 10, and the shoe may then be easily removed.

lVhen a large shoe is to be clamped in the holder the filling piece 8 of Fig. l is omitted, and the clampin member 12 is arranged as shown in Fig. 3 to bear directly against the bottom wall of the opening 7.

Manifestly the capacity of the clamping member 12 to work endwise or slidably through the opening 7, enables the said member 12 to accon'nnodate itself to and securely hold shoes and other pieces of work of various sizes, and in such manner that the shoes or other pieces of work are not scratched or otherwise marred.

I prefer as heroinbefore stated to removably arrange the body member 6 on its stand 1. This provision is made in order that when desired. the member 6 may be removed to give place to a last-support or an appurtenance adapted for the holding pieces of harness while work is being done on the same. The said last-support and harnessholder are not however of the essence of my invention, and I have therefore deemed it unnecessary to illustrate the same.

It will also be noted that incidental to the use of my holder, the spring 16 serves, when upward movement of the pedal lever T is permitted, to open or pull the member 12 away from the body member 6 so that the position of the shoe may be quickly and easily changed.

Having described my invention, What I claim and desire to secure by Letters Patent, is:

1. An expansible work-holder, comprising a body member having guiding means, a clamping member slidably mounted and movable endwise in said guiding means, means connected with said slidable member, at one side of the body member, for moving the clamping member and securing work between the same and the body member, and a spring for opening the clamping member, attached to said member at the opposite side of the body member.

2. An expansible Work-holder, comprising a body member having a transverse opening, a clamping member loose in said opening and movable endwise therethrough, a retractile spring connected to said clamping member at one side of the body member, and a pedal lever connected with the clamping member at the opposite side of the body member.

3. An expansible work-holder comprising a body member having a transverse opening, a filling-piece removably arranged in the lower portion of said opening, a clamping member loose in said opening above the filling piece and movable endwise through the opening, a ret 'actile spring connected to said clamping member at one side of the body member, and a pedal lever connected with the clamping member at the opposite side of the body member.

4. In a work-holder of the expansible type, the combination of a body member having a facing of soft material and also having a transverse opening, a clamping member loose in and movable endWise through said opening, and means for moving said clamping member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
